BASE [FOR ROCKlNG-CHAERS, 8M3.

EPEOIFICATION forming part of Letters Patent No. 319,397, dated June 2, 1885.

(No model.)

To aZZ whom it may concern:

Be it known that I, MARTIN V. B. EvnssoN, of Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Bases for Rocking-Chairs, 850.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in bases for rocking-chairs, cradles, and hobby-horses; and it consists in a base which rests solidly upon the floor, and which has inclined surfaces at each end for the rollers which are attached to the chair, cradle, or hobby-horses to move upon, and suitable means for preventing the rollers from becoming displaced from the inclined surfaces, as will be more fully described hereinafter.

The object of my invention is to provide a base for rocking-chairs, cradles, and hobbyhorses, or other such articles, and which will rest solidly upon the floor, and which, while it allows a rocking movement, will prevent the cradle, chair, or hobby-horse from upsetting.

Figure l is a vertical section. Fig. 2 is a plan viewof a base embodying my invention.

The base is composed of the two pieces A, which rest solidly upon the floor, and which are connected rigidly together by means of cross-pieces B. The centers 0 of thesepieces A are raised upward to any suitable extent, and upon each side of these centers is formed an inclined and preferably curved surface, 1), upon which rest the rollers F of the base G, to which the cradle or hobby-horses are secured.

In order to prevent the rollers from having any lateral movement, a flange, H, is formed upon the outer side of the inclined surface, so as to catchagainst the outer edge of the rollers, and thus prevent the base of the chair, hobby-horse, or cradle from moving laterally upon the pieces A.

In order to prevent the base G from being raised upward, suitable guards, I, are used, which guards may either catch over the tops of the rollers, or over the hubs of the wheels,

or the ends of the axles, as may be preferred.

I do not limit myself to any precise method of forming these guards, for they may be applied in many ways. If desired, an ornament-a1 covering may be applied to the outer side of the pieces A, which will extend up above the guards, and thus hide them from View and prevent articles from getting caught by the rollers.

The base G, to which the chair, cradle, or hobby-horse is secured, consists of the two pieces which extend parallel with the side pieces, A, and which are united together at their ends by means of the cross-pieces J. The axles L, upon which the rollers are placed, are journaled upon the under sides of the ends of these pieces J, as shown. The ends of the axles may be made to project beyond the outer sides of the rollers, and thus be made to catch under the guards and prevent the base II from being raised upward. The base G, in moving back and forth, has the rollers at one end rise up upon the incline at one end of the pieces A, while the other pair of rollers are descending the inclines at the other end, and in this manner a pleasant and even rocking movement is produced without the slightest danger of the chair, cradle, or hobby-horse upsetting in case too much force is applied. When the rollers reach the top of one of the inclines, the guards prevent any further movement, and thus it will be found impossible to cause the chair, cradle, or hobby-horse to tilt backward.

By means of the construction above described all the danger attendant uponthe use of any article having a rocking movement is done away with.

Having thus described my invention, I claim-- 1. A base for rocking-chairs, cradles, and

hobby-horses, consisting of base-pieces A, are secured, and which is provided with roll- IO which have suitable inclined surfaces formed ers for moving upon the inclined surfaces,

upon them, in combination with the base prosubstantially as set forth. vided with rollers which move upon the ini In testimony whereof I affix my signaturein olined surfaces, substantially as shown. presence of two Witnesses.

2. The combination of a base composed of MARTIN V. B. EVESSON. the pieces A, having inclined surfaces, and Witnesses: provided with suitable guards, with the base GEO. W. WRIGHT, to which the chair, cradle, or hobby-horses HART ABRAIIAM.
